When Lin Tian wakes up, he is neither a prince nor a good-for-nothing. He has become the last surviving heir of the rundown Shenji Sect, and, on top of that, a man buried in a mountain of spirit-stone debt. With creditors at the door and the sect facing expulsion, he looks at the pile of junk the previous owner ruined while refining, then at his degree in mechanical engineering from a top university and the interface of his [Craftsman's Heart for All Things System]. "Fellow cultivator, have you ever heard of... a lifetime warranty?" From then on, the world of cultivation goes completely off the rails.
Flying swords have to be fast, but do they also need to pass aerodynamic testing? A furnace's worth isn't determined by its origins, but by its thermal efficiency, conversion rate, and automated controls? A sect-protecting formation gets upgraded straight into a distributed rune-computing array?
When an ancient demon carrying a "Chaos Virus" that corrupts every magical artifact descends, the entire cultivation world despairs. Then Lin Tian steps forward without a hint of panic.
"Don't panic. It's a small problem."
"It's just a large-scale DDoS attack. I'll patch everyone's treasures, then set up a firewall for you."
"Demon, your protocol's underlying layer has a fatal vulnerability. Take this 'Ping of Death'!"
He is creative, but the male protagonist does not want to improve his own strength, which really shows that he lacks IQ and is too naive.
